EDWIN EAGLES, OF-MAMARONEGK, NEW YORK, ASSIGNOR TO HIMSELF AND J. H. GUION, OF SAME PLACE.

IMPROVEMENT IN INSULATORS FOR LlGH-TNlNG-CONDUCTORS.

Specification forming part of Letters Pmat N a9,'c13,aatea August 18,1863.

To all whom it may concern.-

Be it known that I, EDWIN EAGLES, of Mamaroneck, in the county of Westcfiestcr and State of New York, have invented certain new and useful Improvements in Insulators for Lightning-Conductors; and I do hereby declare that the-following is a full, clear, andexact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical sectional view 'of an insulator with my improvement adapted for the walls or sides ofbuildings. Fig. 2 isa plan view corresponding with Fig.1. Fig. 3is a side 'iew of'tliednsulator adapted to the roofs of buildings. Fig, 4 is a perspective view of the support which I use for roofs.

Similar letters of .ference indicate corresponding parts in the several figures.

This invent-ionconsists in a certain mode of combining the holder with the insulator, by

which it is enabled to be set at any angle nec-,

essary to adaptitself to the direction of the,

conductor, so that the same insulator may be made to serve equally well for walls or roofs.

It also consists in a certain construction of the support by which it is better adapted to roofs.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A is the glassinsulating-block,having firmly secured within it an iron pin, B, in the bottom of which is a socket or hole for the reception of the shank of the holder (3, which receives the conductor, the said shank being at a right angle with the pin'B.

D is the support for theinsulator, made with a long shank, a, to be driven or screwed into the building.

The glass block Ais madeof square or other polygonal form in its horizontal section, that it may be incapable of turning within the eye (1 of the support D, which is made of corresponding form, and the said glass is made .with a shoulder, g, to rest upon the support.

It is also made with a cavity, f, in its bottom, to preventrain or' moisture which runs oh its top and sides from collecting around the pin B and thereby destroying the insulation. The

' pin is secured in the glass by making its up provided in the lower part of the pinB for its reception, thatwhile it may be turned therein it will retain itself in place. It maybe better to have a p n inserted through the shank c to secure the holder eifectually.

By the above mode of combining the holder 0 with the, insulator it will be readily understood that the said holder may be adjusted to suit any direction of th e conductor, from vertical to horizontal, by simply turning its shank in the socket e of the pin B.

Fig. 1 shows the arrangement of the holder for vertical portions of a conductor, and Fig. 3 shows it arranged in a position of right angles to Fig. 1,tc adapt it to aportion of acouductor passing over a roof.

The support shown in Figs. 3 and 4 dillers from that shown in Figs. 1 and 2, and from all ordinary insulator-supports, in havingi ts shank a at right angles to its eye d, which enables the block A and pin B to be kept in upright or nearly upright positions in passing over a roof, the eye (1 being allowed to assume a horizontal position when the shank a is driven or screwed into the roof.

What 1 claim as my invention, and desire to secure by Letters Patent, is

1. The fitting'of the shank c of the holder 0 to a socket or hole, 6, in the pin B, which attaches it to the glass A, substantially as and for the purpose herein described.

2. The support D, having its eye (1 for the reception of the glass, set at a right angle toits shank or stem A, substantially as and for the purposes herein specified.
